认知冲突是当个体意识到个人认知结构与环境或是个体认知结构内部不同成分之间的不一致所形成的状态。如何提高课堂教学有效性是一线教师思考、探讨、亟待解决的首要问题。笔者在不断探索、与同行的交流及阅读相关学术研究报告后,摸索出提高课堂有效教学的若干方法。本文就《化学反应原理》教学中,如何通过设置认知冲突提高课堂教学效率举例说明。一、利用实验现象设置认知冲突,提高课堂教学效率化学是一门以实验为基础的自然科学,化学实验所展示
Cognitive conflict is formed when the individual realizes that the individual cognitive structure and the environment or the inconsistency between different components of the individual cognitive structure. How to improve the effectiveness of classroom teaching is one of the most important issues to be solved by teachers in the field. After continuous exploration, peer-to-peer exchange and reading related academic research reports, I explored ways to improve effective teaching in the classroom. This article gives an example of how to improve the efficiency of classroom teaching by setting cognitive conflicts in the teaching of “Principles of Chemical Reaction”. First, the use of experimental phenomena to set the cognitive conflict and improve the efficiency of classroom teaching Chemistry is an experiment based on natural sciences, chemistry experiments show
